php - Joomla 3! Module Parameters
I have a Joomla website where I have a custom module with mod_myModuleName.php and mod_myModuleName.xml files and a folder where there are several PHP scripts that add special functionality to my module. There is a config.php file in the folder that holds an associative array with variables and their values hard-coded. The module works just fine.
What I want though is to provide administrator area for the values of the variables in the array, so that I can put values in administrator panel and get their values in config.php. In my mod_myModuleName.php I use<?php echo $params->get('param')?> and it works like a charm.
But when I try to use the same technique in the config.php it breaks my code. I tried to get the values in mod_myModuleName.php and then include it in config.php and use the variables but it does not work either. I have not got so much experience in php and cannot understand what can be the reason.
It sometimes gives me an error of something non object and I guess it must be something connected with object oriented php, am I right? And if so is there a way to overcome this without object orientation or how can I solve my problem?

Solution:
The problem will be with the way you're using your
config.php.When your modules entry point file
mod_myModuleName.phpis loaded by Joomla the$paramsobject is already available in that context, you need to provide it to your scripts.If you look at something like the
mod_articles_latestmodule you will notice that the helper class is included with this line:And then helper class is has it's
getList()method called statically with the$paramspassed into it, so that$paramsis available to class context:Inside the helper class
ModArticlesLatestHelperyou will notice that thegetList()expects the$paramsto be passed in.I would strongly recommend reading the articles in the Modules section of Developers Portal on the Joomla Doc's.
Try the "Creating a simple module" article.
